Answer 1

Let's clarify what is being asked.

You have two lines representing expressions of addition:

• Line 1: 4 plus 6 (4 + 6)
• Line 2: 6 plus 4 (6 + 4)

In terms of dots, we can represent the numbers as follows:

Line 1 (4 + 6):

• 4 can be represented as ●●●● (4 dots).
• 6 can be represented as ●●●●●●● (6 dots).
• The expression can be rewritten as: ●●●● plus ●●●●●●●

This totals to 10 dots.

Line 2 (6 + 4):

• 6 can again be represented as ●●●●●●● (6 dots).
• 4 can be represented as ●●●● (4 dots).
• The expression can be rewritten as: ●●●●●●● plus ●●●●

This also totals to 10 dots.

Summary:

Both Line 1 and Line 2 involve 10 dots representing the sums of 4 + 6 and 6 + 4, respectively.

So in the answer to your attempted question:

• Line 1 represents 4 plus 6 with a total of 10 dots.
• Line 2 represents 6 plus 4 with a total of 10 dots.

Despite the different order of summands, the total remains the same.
